To all whom it may concem:

Be it known that I, Gnoncn Lnn MILLER, a citizen of the United States, residing at Canton, the county of Stark and State of Ohio, have invented certain new and useful Improvements in Apparatus for Gau ing Taper Pieces, of which the following 18 a specification.

This invention relates to an apparatus for gauging taper pieces, and more particularly to a manually operated device which con- 7 v templates the gauging of taper rollers by the method disclosed in my prior Patent No. 1,367,199, dated February 1, 1921, which method consists broadly in introducing the taper pieces into an open ended taper socket and bringing the end portion of the taper piece into contact with a gauging member.

The objects of the invention are to provide simple and thoroughly ethcienu manually operated apparatus for quickly and accurately gauging taper pieces, and more particularly the rollers for taper roller bearings.

With a method at present employed for manufacturing roller hearings in order to increase the production and cheapen the manufacture the rollers and cones are roduced in automatic machines. This met od results in the production ofecones and rollers which vary somewhat in dimensions.

It is found in practice that a considerable number 'of the cones, as well as the rollers, will be above standard size and substantially the samenumber will be below standard size. By selecting rollers which are very close to standard size they may be introduced into a bearing having a cone or standard size, and thus produce a bearing of standard size; by selecting rollers below the standard size and introducing them into a hearing having a cone above standard size, the result is to produce a bearin of standard size; and by selecting rollers w ich are above standard size for a hearing having a cone below standard size the result is to produce a bearing of standard size.

From the foregoing, it will be seen that it is highly important to carefully gage the rollers, in order that all the rollers in a given hearing may perform their functions in the proper manner.

. a Accurate gauging'and asserting of the rollers by the method of measuring diderences .in diameters of the rollers is price.

tically impossible, owing to the slight variations in the diameters or the rollers; and in accordance with the present invention the taper rollers are introduced into an accurately prepared'taper' socket from which they protrude, and the protruding ends arecarried past an indicating device which. registers the size or the roller.

It will be seen that a va slight variation in the'dia'meter of the re er will. make a very considerable difierence in the distance which the roller will project from thesocket; hence, by following the method here referred to, it is possible to attain great accuracy in gauging the rollers without the necessity of the utmost accuracy in the construction of the apparatus for eiiecting this result.

In accordance with the presentinvention the taper rollers are introduced into a taper socket mounted upon an oscillating arm and arranged to be moved beneath the plunger of an indicating device, which accurately gages the size of the roller, means being provided for automatically releasing the corresponding parts throughout the draw- The machine comprises the base 1 arranged to be mounted upon a bench or table 2, as by the clamp 3 and is provided with the preferably rearwardly inclined upright 4.
